FASTELFILM HPB-600 THERMAL BONDING AND SEALING FILM

FastelFilm HPB-600 Heat Activated Adhesive Film

FastelFilm HPB-600 (150F/66C) is designed for applications that require higher bond strength against lower energy surface as well as require low melt point heating. FastelFilm HPB-600 is an EVA/Synthetic Rubber blend thermoplastic adhesive system available in a wide range of film thicknesses and film delivery formats (rolls, narrow rolls, die cuts).
FastelFilm HPB-600 is popular within the medical device and diagnostic application market for its low melt point temperature that can benefit reagent/biologic heat sensitivities exist that may exist. FastelFilm HPB-600 can be utilized as an adhesive interface bonding 2 substrates together or as a low melt sealing gasket.
With a flow characteristic that can be controlled with heating, FastelFilm HPB-600 can be provided in a manual drop-in-place or automated die cut format providing efficient heating cycles as well as no clean-up after heating. FastelFilm HPB-600 can be die cut to match a wide range of mounting and sealing applications areas. Once the adhesive pad is heated to or past its melt point temperature and cooled, the adhesive is set. Re-work can be acheived by re-heating to re-position or disassemble. With the option of the tacky version (HPB-600-PT), adhesive pad placement or substrate pre-fixturing at room temperature is advantageous for assembly.

DOE Testing (design of experiment)

When designing a new product, experimenting to determine the suitability of our products within the scope of your applications is key. Fastelfilm can be heated using commercially available or custom heating devices such as heat presses, ovens or heated rollers. Prior to testing FastelFilm, we encourage our customers to perform a DOE (design of experiment) based upon the FastelFilm melt point and substrates being bonded as well as other subsequent application sensitivities that may exist. Since all of our customer applications involve various substrate types, substrate thicknesses and heating devices, we strongly encourage our cusotmers to understand the relationship between your heating device's set temperature and what temperature is yielded at the bond line (area where the FastelFilm resides). Understanding the relationship between set temperature and bondline temperature will significantly help narrow the scope of DOE combinations and shorten your process towards optimization.

Preparation | Installation Guidelines

The following are general guidelines to be used as a preliminary basis to determine suitibility of FastelFilm. The below stated values are to be used as a starting point only and should be further tested to determine optimal heating time, temperature and pressure in order to yield the desired result. Since FastelFilm has no pre-determined heating time beyond heating to or past its melt point, it is important to understand the relationship between heating time, heating temperature and pressure applied during heating in order to optimize installation.
HPB-600 Softening Pont | Max Heating
Softening Point: 50C Melt Point: 66C (full liquid state) In order to acheive continuous temperature stability in field use, softening point should be higher than your device's established maximum operating temperature or higher than any post bonding internal temperature stability testing that may be required. Maximum Processing Heating Temperature FasteFilm HPB-600 can be heated alongside other materials that require higher heating. Maximum process heating temperature of the FastelFilm HPB-600 is 150C. Prolonged heating exposure above this temperature may result in adhesive damage.
Surface Preparation
All surfaces should be clean and free debris. Surface can be cleaned with Isopropyl Alcohol (IPA) or solvent. All surfaces should be dry prior to installing adhesive. Additonal surface treatments may be considered depending on substrate material type and application requirements. CORONA TREATED SURFACES Corona treated surface modification may be a benefit depending on substrate material type. Customer testing required.TEXTURED SURFACES Textured surface may be a benefit in order to create more surface area depending on substrate type. Customer testing required.ADHESION PROMOTERS It is important for customers to determine compatability of adhesive promoter treatment.
Tack Temperature
Type HPB-600: 55C to 70C Liner note: adhesive pad should be handled with carrier liner. Heat through carrier liner to transfer heat. Once cooled, remove liner. Maintain adequate surface contact pressure during this process. HPB-600-PT (TACKY FILM) - heat not required. Press firm against surface. Peel away liner. Dwell time may vary depending on substrate type or environmental temperature. Testing required.
Full Bond Heating Temp
68C to 90C+ Heating temperature stated is at bond line (area where adhesive film resides). Necessary to acheive adequte wet-out of the adhesive onto the substrates. Adhesive should not be exposed to temperatures above 300F / 150C. HPB-600-PT Note: for tacky film version, tack does not diminish after heating. Tackiness remains post heating.
Heating Pressure
3 PSI to 100 PSI+ Important to maintain good surface contact of the adhesive to the substrates. No set pressure required. Dependent on substrate type, thickness, interface area as well as substrate durability.
Heating Time
3 seconds to 30 seconds (variable)
No set heating time required. Dependent on thermal conductivity of substrates and heating devices. Minimum melt point must be acheived. No complex ramp up and ramp down patterns required unless other materials require this during the heating process.
Cooling (set) Time
Variable
Adhesive should be allowed to adequately cool below its melt point before applying stress. It is recommended (not required) to maintain pressure during cooling to promote surface contact during this process. Forced direct air systems okay to accelerate cooling.
Re-Work or Clean Up
68C to 90C+ While adhesive remains in its melted open state, disassemble substrates. For re-bonding, it is recommended to clean interface area and apply new adhesive pad. Traditional solvents (biosolvent or mineral spirits) or Isopropyl Alcohol (IPA) can be used to clean adhesive. Slight heat can also be applied to surface adhesive residue and wiped clean while adhesive is in softened state.
Viscosity Note
Fastelfilm is designed with a specific melt point temperature. Flow control within its melted state is a function of heating temperature and pressure. As the adhesive is heated further past its melt point temperature, its viscosity continuously decreases. Significant pressure within a low viscosity state can cause adhesive run-out outside the interface.
Interface Contact
Depending on your heating application setup, an interface pad between the heat source and stack-up may be considered to provide conformability across large interfaces. Soft, mid and hard durometer thermally conductive gap pads can be considered in order to minimize the temperature drop from heat source to bond line (area where Fastelfilm resides).
Heating Equipment
Heating can be acheived through the use of off the shelf standard heating equipment such as heat presses, ovens or heated rollers.
