Frequently Asked Questions
Q What is the main application of the AS 8550 / AS 8575H polyester resin?
AS 8550 / AS 8575H is primarily designed for high-end electronic Mylar products. It delivers high initial tack, high peel strength, and high tensile elongation, making it ideal for bonding PET/AL, copper (CU), and other specialty film materials used in the electronics and coatings industries.
Q What makes SR 39-16 suitable for metal-to-PET bonding applications?
SR 39-16 is a soft resin featuring high molecular weight and low glass transition temperature (Tg). These properties provide excellent adhesion between metal and PET substrates, combined with high temperature resistance and high peel strength. It is widely used in mica decorations, reflective adhesives, inks, coil coatings, and adhesive formulations.
Q How does HR 2564 differ from SR 39-16 in terms of resin characteristics?
Unlike SR 39-16 (a soft resin with low Tg), HR 2564 is a hard resin with high molecular weight and high Tg. This makes it particularly suited for self-drying primer coatings on metal sheets and metal films, offering outstanding adhesion to demanding substrates like stainless steel.
Q What equipment types are compatible with these polyester resin products?
AS 8550 / AS 8575H is compatible with dry-type laminating equipment. SR 39-16, HR 2564, and CR 21-12 are all designed for use with coating machines. None of these models are currently formulated for flexo printing or solvent-free laminating equipment.
Q What are the key properties of CR 21-12 that make it suitable for heat-seal primer coatings?
CR 21-12 is a semicrystalline resin with high molecular weight and low Tg. Its low Tg ensures no blocking occurs during storage or processing, making it an excellent self-drying heat-seal primer coating for various metal sheets, metal films, and metal wires, while also providing strong encapsulation performance.
Q Are these polyester resins resistant to extreme temperatures?
Yes. The entire product line (AS 8550/AS 8575H, SR 39-16, HR 2564, and CR 21-12) is formulated from high molecular weight polyester materials that are resistant to both high and low temperatures. They maintain strong adhesion to metal sheets, glass, and various films even under demanding thermal conditions.
