Purathane Part A Two Pack Hardener by Urethane Coatings - Polyurethane Specialists Since 1979

Purathane Part A two pack (hardener)


URETHANE COATINGS PURATHANE TWO PACK is two component water borne polyurethane finish developed to provide your commercial timber and parquetry floors with extremely hardwearing and long lasting protection. The rapid curing of PURATHANE TWO PACK achieves optimal hardness up to 50% faster than single pack water borne polyurethane and higher solids provide greater resistance to wear.
Because water is used as the alternative carrier to solvent, URETHANE COATINGS PURATHANE TWO PACK emits low VOC’S (volatile organic compounds) and is therefore user and environmentally friendly but retains all the durable and hard wearing benefits of solvent based polyurethane.

Shake each container for one minute and allow each to stand for two minutes, then Mix PURATHANE PART B (BASE) and PURATHANE PART A (HARDENER) at a ratio of 10 to 1 and thoroughly stir, then allow the mixture to stand for two minutes. Always add PURATHANE PART A (HARDENER) to PURATHANE PART B (BASE). Mixed PURATHANE TWO PACK has a pot life of 2 hours (@ 25ºC and 50% R.H.). Smaller mixtures (< 2 Litres) and increased temperature and/or reduced humidity will reduce pot life.
