Frequently Asked Questions (FAQ)
Q What makes 61003A superior to traditional epoxy acrylates?
Traditional epoxy acrylates frequently suffer from brittleness and yellowing despite their high curing speeds. 61003A resolves these structural issues through molecular optimization, offering excellent flexibility, impact resistance, and enhanced UV aging resistance while maintaining high curing reactivity.
Q What is the operational viscosity and functionality of this resin?
61003A has a viscosity range of 8000 to 18000 mPa.s when tested at 60ºC and features a functionality of 2 with a low acid value (≤8 mgKOH/g), ensuring stable processing and reliable cross-linking.
Q How does 61003A perform in electronic encapsulation and potting?
When used as a primary resin for UV potting compounds, its balanced flexibility, tough matrix, and superior adhesion effectively protect delicate electronic components from mechanical stress cracking and environmental erosion.
Q What are the packaging options available?
The product is supplied in opened ordinary steel drums available in both 20 kg and 220 kg packaging configurations.
Q What storage precautions must be taken to ensure stability?
61003A must be stored in dark, opaque containers with corrosion-resistant coatings at temperatures below 35 ºC. At least 15% air headspace must remain in the drum to maintain stability, and direct sunlight exposure must be strictly avoided. The guaranteed shelf life is 180 days under these conditions.
