Frequently Asked Questions (FAQ)
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 products. They share key properties including high initial tack, high peel strength, and high tensile elongation, making them suitable for bonding PET/AL, CU and other demanding substrate combinations. The specific formulation differences are tailored to particular application requirements — please consult our technical team for detailed selection guidance.
Q
What types of equipment are compatible with SR 39-16, HR 2564, and CR 21-12?
SR 39-16, HR 2564, and CR 21-12 are all designed for use with coating machines. They are not intended for dry-type laminators, flexo printing equipment, or solvent-free laminating machines. Please ensure your production line uses a compatible coating machine before selecting these products.
Q
What makes SR 39-16 suitable for mica decorations and reflective adhesive applications?
SR 39-16 is a soft resin with high molecular weight and low glass transition temperature (Tg). Its excellent adhesion between metal and PET substrates, combined with high temperature resistance and high peel strength, makes it ideal for mica decoration applications and high-adhesion reflective adhesive fields. It is also widely used in inks, coil coatings, and adhesive formulations.
Q
Can HR 2564 be used as a primer coating for stainless steel?
Yes. HR 2564 is a hard resin product with high molecular weight and high Tg, specifically designed as a self-drying primer coating for metal sheets and metal films. It demonstrates excellent adhesion to a variety of metal sheets, including stainless steel, making it a reliable choice for metal surface primer coating applications.
Q
What are the key advantages of CR 21-12 for heat-seal primer coating applications?
CR 21-12 is a semicrystalline resin with high molecular weight and low Tg. Its low Tg ensures no blocking during storage and processing, making it highly suitable for heat-seal primer coatings on various metal sheets. It also provides good adhesion and encapsulation performance for metal sheets, metal films, and metal wires, and is applied in a self-drying process for ease of use.
Q
Which product is recommended for coatings, inks, and metal sheet coating fields?
All four products in this series — AS 8550/AS 8575H, SR 39-16, HR 2564, and CR 21-12 — are applicable to coatings, inks, and metal sheet coating fields. The best choice depends on your specific performance requirements: AS 8550/AS 8575H for dry-type laminating with high peel strength needs; SR 39-16 for soft, flexible adhesion with high temperature resistance; HR 2564 for hard, high-Tg primer coatings; and CR 21-12 for heat-seal primer coating with no-blocking properties.
