Trubuild Efx 666 - Two Part PU Modified Hybrid Epoxy Adhesive
TRUBUILD EFX 666 is two component PU modified hybrid epoxy adhesive for high performance and high adhesion for fixing tiles with no vertical slip-on deformable substrates. It is suitable for metal, plywood, cement board and dry wall construction. Designed for absorbent and non- absorbent substrates
It Complies to EN 12004:2017 “R2T” ,“Type-5” TS2 as per IS 15477:2019 and CFTRI approved.
SURFACE PREPARATION AND APPLICATION
Preparation of substrates must be compact and consistent, free from dust, oil, algae fungi, efflorescence and grease, free from any rising damp, with no loose, flaky, or imperfectly anchored parts. The substrate must be sound, without cracks and have already completed 28 days curing period of hygrometric shrinkage. Uneven areas must be treated with suitable Polymer modified mortar & concrete. TRUBUILD EFX 666 is prepared by mixing together parts A and B from the bottom upwards, using a low-rev (≈ 400/min.) helicoidal agitator, respecting the pre-set ratio of Part A: Part B:: 4 : 1, (by weight) of the packs. Pour part B into the bucket containing part A, being careful to mix the two parts uniformly until a smooth, even coloured mixture is obtained (Minimum 5-7 minutes mixing). The user must mix a quantity of adhesive which can be consumed within 1 hour at +27 °C / 65% R.H. Application TRUBUILD EFX 666 must be applied with a suitable, notch trowel. Using the smooth part of the spreader, apply a fine layer of product, pressing down on the substrate in order to ensure maximum adhesion. Press down each tile to allow for maximum coverage of the surface. If the substrate is subjected to heavy traffic, in external applications and wherever high-elasticity laying system is required, use the double-spread technique to ensure 100% application of the product to the rear of the tiles. For vertical application it will be ideal to use initial supports as per standard construction practice to hold the tile in its original alignment.
NOTE-1. For fixing any plastic / metal / polymer sheets / or any material a patch test is advisable to ensure proper bonding with the substrate before going for the larger application.
NOTE-2. Ensure entire tile coverage of chemical and consumption may vary as per texture, porosity and undulation of substrate

CURING
Allow curing for 24 hr before foot traffic and other work like Grouting between the tile.
24 Month from the date of manufacturing, Store in a cool & dry place in temperature +10 °C to +35 °C in unopened condition in its original packing and keep away from direct sunlight/Rain.

LIMITATION & PRECAUTIONS
Strictly keep to the mixing ratio of Part A: Part B:: 4 : 1, (by weight). For partial mixing, weigh the two parts precisely - workability times may vary considerably, depending on environmental conditions and the temperature of substrate and environment. Protect against direct rain for at least 12 hrs after application. Do not lay on substrates subject to moisture rising or which are not completely cured. Before application the substrate should be completely dry condition. Avoid application during rain open to sky. For any special application, please seek the advice of Trubuild Technical service Team.
CLEANING
Trubuild EFX 666 can be removed from tools and equipment immediately after use with thinner, hardened material can be removed mechanically or it may get waste
