How can I improve impact resistance to prevent resin from cracking?

Why Impact Resistance Is Crucial

Epoxy resin is popular for its strength and glossy finish, but standard resins can be brittle under sharp impacts or repeated use. Areas like tabletops, coasters, and kitchen counters often face dropped items or minor collisions. Without the right protection, these everyday stresses can result in unsightly cracks or chips.

Choosing Flexible Coatings for Protection

Opting for a flexible topcoat is an effective way to enhance a resin surface’s resilience. Flexible polyurethane coatings absorb the energy from impacts rather than transmitting it directly to the resin layer below. For projects up to 0.5 m², Heat Pro Flexible Heat-Resistant Glossy Coating is designed to combine elasticity with heat resistance and a high-gloss finish. This makes it especially suited for coasters, trays, and small tabletops that face both thermal and physical stresses.

Practical Tips for Application

• Always apply flexible coatings to surfaces that are fully cured, clean, and dry for best adhesion.
• If working with acrylics or coloured surfaces, test a small area first to ensure compatibility with the coating you’ve chosen.
• Mind the recommended maximum surface area when using products like Heat Pro to ensure a consistent and smooth result.
