Hardtop AX

Hardtop AX

"Buy Hardtop AX with Free Shipping to Mainland UK."

A two-pack glossy polyurethane topcoat with excellent gloss and colour retention.  Suitable for brush/roll as well as spray application.  Hardtop AX has good chemical resistance and can be used in aggressive atmospheric environments.

Easier to use than many 2 pack polyurethanes (particularly when brushing and rolling),  Hardtop AX gives a glossy, durable finish.  It offers high sag resistance, low level of spray dust, low odour and a consistent gloss.  Hardtop AX has much better abrasion and chemical resistance that Hardtop XP.

High volume solids (63%) compared to traditional polyurethanes results in low VOCs making it a modern topcoat with a lower environmental impact.

Available in 5 litre & 20 litre sizes.
