Frequently Asked Questions (FAQ)
Q
What are the main application fields for the AS 8550 / AS 8575H polyester resin products?
AS 8550 and AS 8575H are primarily used in coatings, inks, and metal sheet coating fields. They are especially suited for high-end electronic Mylar products that require high initial tack, high peel strength, and high tensile elongation, making them ideal for PET/AL, CU, and other substrate materials.
Q
What makes SR 39-16 suitable for metal-to-PET bonding applications?
SR 39-16 is a soft resin product with high molecular weight and low Tg, which gives it excellent adhesion between metal and PET substrates. It also offers high temperature resistance and high peel strength, making it highly effective for mica decorations, high-adhesion reflective adhesive applications, inks, coil coatings, and adhesives.
Q
How does HR 2564 differ from SR 39-16 in terms of resin properties?
HR 2564 is a hard resin product with high molecular weight and high Tg, in contrast to SR 39-16 which is a soft resin with low Tg. HR 2564 is designed as a self-drying primer coating for metal sheets and metal films, offering excellent adhesion to metal surfaces such as stainless steel. SR 39-16, on the other hand, focuses on flexible bonding and high peel strength applications.
Q
What is the advantage of CR 21-12 being a semicrystalline resin for heat-seal primer coatings?
CR 21-12's semicrystalline structure combined with its high molecular weight and low Tg provides good adhesion and encapsulation to metal sheets, metal films, and metal wires. Its low Tg ensures no blocking issues, making it particularly suitable for heat-seal primer coatings on various metal sheets in a self-drying application process.
Q
Which of these polyester resin products are compatible with coating machines?
SR 39-16, HR 2564, and CR 21-12 are all compatible with coating machines. AS 8550 / AS 8575H is designed for dry-type laminating equipment. The choice of product depends on the specific substrate, application requirement, and equipment configuration.
Q
Are these polyester resin products suitable for both high-temperature and low-temperature environments?
Yes. The high molecular weight polyester materials in this product line, particularly AS 8550 / AS 8575H, are engineered to be resistant to both high and low temperatures. This thermal stability, combined with excellent adhesion to metal sheets, glass, and various films, makes them reliable for demanding industrial environments with wide temperature ranges.
