Opti-tec 4200 Optically Clear Polyurethane Encapsulant & Potting Compound

From £12.80 (£15.36 inc. VAT)

Opti-tec™ 4200 is a clear, water-white polyurethane resin designed for the encapsulation of electronics, LEDs, electrical products and other items where high transparency and aesthetics are important. Opti-tec 4200 optically clear potting compound has excellent non-yellowing colour stability, due to the incorporation of both UV resistant base materials and the addition of UV stabilisers and antioxidants.

Opti-tec 4200 is used for a range of applications from high value LED panels to decorative giftware (e.g. flower impregnation). It is also an excellent resin for the doming of badges, labels and decals.

An evaluation kit is available which includes one 50g cartridge supplied with a dispensing gun and mixing nozzles.

Opti-tec 4200 is available in a translucent milky-white version (Opti-tec 4220).
