Frequently Asked Questions (FAQ)
Q
What is the difference between AS 8550 and AS 8575H in terms of application?
A
Both AS 8550 and AS 8575H are high molecular weight polyester materials designed for high-end electronic Mylar products. They provide high initial tack, high peel strength, and high tensile elongation, making them ideal for bonding PET/AL, CU, and other specialty film materials used in electronic applications.
Q
What types of equipment are compatible with SR 39-16, HR 2564, and CR 21-12?
A
SR 39-16, HR 2564, and CR 21-12 are all compatible with coating machines. They are not designed for dry type laminating, flexo printing, or solvent-free laminating equipment, making them specifically optimized for coating machine applications.
Q
What makes SR 39-16 suitable for mica decorations and reflective adhesive applications?
A
SR 39-16 is a soft resin with high molecular weight and low glass transition temperature (Tg), which gives it excellent adhesion between metal and PET substrates. Its high temperature resistance and high peel strength make it particularly well-suited for mica decorations and high-adhesion reflective adhesive fields, as well as inks, coil coatings, and adhesive applications.
Q
How does HR 2564 differ from SR 39-16 in terms of resin properties?
A
HR 2564 is a hard resin product with high molecular weight and high Tg, whereas SR 39-16 is a soft resin with low Tg. HR 2564 is specifically formulated as a self-drying primer coating for metal sheets and metal films, offering excellent adhesion to substrates such as stainless steel, making it ideal for demanding metal coating applications.
Q
What does "semicrystalline resin" mean for CR 21-12, and why is it beneficial?
A
CR 21-12 being a semicrystalline resin means it has a partially ordered molecular structure, which contributes to its good adhesion and encapsulation performance on metal sheets, metal films, and metal wires. Its low Tg ensures no blocking occurs during storage or processing, making it highly suitable for heat-seal primer coatings on various metal sheets in a self-drying format.
Q
Are these polyester resin products suitable for both high-temperature and low-temperature environments?
A
Yes. The high molecular weight polyester materials in this product line — including AS 8550 and AS 8575H — are specifically engineered to resist both high and low temperatures. They maintain excellent adhesion to metal sheets, glass, and various films across a wide temperature range, ensuring reliable performance in diverse environmental conditions.
