Production Description:
Gtech-604 Elastomer Waterproofing Material is originally designed to apply over concrete and
its advanced elongation is suitable for bridging stress cracks in concrete and other
substrates.Gtech-604 is the state of the art 100% solids, ultra fast cure, flexible, spray-applied, high
build, two component aromatic pure polyurea elastomer. The system consists of A component, a
quasi-prepolymer rich of free NCO, and B component, a mixture of polyetheramines, amine
extenders and other additives. With high elongation value, Gtech-604 has great memory, It can be
used waterproofing and can be applied on geotextiles fabrics. Gtech-604 can produce an extremely
tough film at all thicknesses; it may be applied in all positions and to any suitably prepared substrate.
Gtech-604 is relatively moisture and temperature insensitive, allowing application in the most
problematic ambient conditions. It is the optimum choice where a tough, flexible, impact resistant,
abrasion resistant waterproofing system which exhibits extraordinary performance characteristics.
Advantages:
1. Fast cure, short down time, no sagging
2. Excellent Physiochemical Properties
3. Bondable and paintable to various kinds of substrates
4. Ambient insensitive, good thermal stability
5. 100% Solids, No VOC's, Odorless, No Toxic Vapors
6. Good resistance to a wide range of chemical attack
7. Excellent Skidding Resistant, Anti-corrosion and Waterproof Properties
8. Good weather ability, Added color stability
9. Seamless, flexible, slick and non-porous
10. No chalking and fading in long-term use outdoors
Recommended Uses:
Gtech-604 Elastomer Waterproofing Material is an ultra fast cure system; it can be applied at
thicknesses of several ten millimeters, or greater, in a single application. It can be widely used in:
Liner for aquarium, ponds, lagoons, reservoirs, irrigation ditches etc
Metal, concrete, wood, and foam roofing
Underground engineering
Buried earthen containment lining (with or without geotextiles)
New or existing sub-grade slabs, walls, etc
Truck bed and undercarriage liner
Water & wastewater linings
To requirement of semi-gloss surface and avoiding shine eye, the cure time can be accelerated to
obtain evenly orange peel apparent by directly spraying.
Packaging:
Part A: 220kilogram per drums.
Part B: 200 kilogram per drums.
Notes:
1. Gtech product is intended for industrial use by properly trained professional applicators only.
2. Thoroughly mix container of B component with an air-driven power mixer for a minimum of 15
minutes prior to application.
3. Adding a nitrogen blanket is strongly recommended for use on the "A" component for storage
after opening.
4. It is a 100% solids production, strictly prohibit add any diluents.
5. The quality and fitness of the product is depending upon the proper mixture and application of thecomponent by the applicator.
6. This specification is an accumulation of long term testing and experience. Published technical
data and instructions are subject to change without notice.
