Frequently Asked Questions
Q
What is the difference between AS 8550 and AS 8575H polyester resins?
Both AS 8550 and AS 8575H are high molecular weight polyester resins designed for high-end electronic Mylar applications. They are engineered to deliver high initial tack, high peel strength, and high tensile elongation, making them ideal for bonding PET/AL, copper (CU), and other demanding substrate materials. They are suitable for dry-type laminating equipment.
Q
What makes SR 39-16 suitable for metal-to-PET bonding applications?
SR 39-16 is a soft resin product featuring high molecular weight and low glass transition temperature (Tg). Its formulation provides excellent adhesion between metal and PET substrates, along with high temperature resistance and high peel strength. It is widely used in mica decorations, high-adhesion reflective adhesives, inks, coil coatings, and adhesive applications.
Q
In which applications is HR 2564 most commonly used?
HR 2564 is a hard resin product with high molecular weight and high Tg. It is primarily used as a self-drying primer coating for metal sheets and metal films. It demonstrates excellent adhesion performance on a variety of metal substrates, including stainless steel, making it a preferred choice for industrial coating and metal film lamination processes.
Q
What are the key characteristics of CR 21-12 resin?
CR 21-12 is a semicrystalline resin with high molecular weight and low Tg. It offers strong adhesion and encapsulation performance for metal sheets, metal films, and metal wires. Its low Tg and non-blocking properties make it particularly suitable for heat-seal primer coatings on various metal sheet types, operating as a self-drying system compatible with coating machine equipment.
Q
Which equipment types are compatible with these polyester resin products?
The product range supports multiple equipment types. AS 8550 and AS 8575H are compatible with dry-type laminating machines. SR 39-16, HR 2564, and CR 21-12 are all designed for use with coating machines. This flexibility allows manufacturers to integrate these resins into existing production lines across coatings, inks, and metal sheet coating fields.
Q
Are these resins suitable for high-temperature environments?
Yes. The entire product line — including AS 8550/AS 8575H, SR 39-16, HR 2564, and CR 21-12 — is formulated with high molecular weight polyester materials that provide resistance to both high and low temperatures. This thermal stability ensures reliable performance in demanding industrial environments, including metal sheet coating, electronic component manufacturing, and reflective adhesive applications.
