Crystal Clear Rubber Crumb Binder , Solvent Free Polyurethane Adhesive For Rubber Flooring

General Characteristics

100% solid ,aromatic polyisocyanate -prepolymer moisture curing binder based on diphenylmethane diisocyanate. It is MDI based and solvent free. It exhibits excellent adhesion to all rubber granules and gives a strong performance both in terms of tensile strength and durability.

It is mixed with recycle rubber granules or epdm granules for the creation of the elastics safety flooring safety multi color or other flexible rubber flooring , ideal for playgrounds, athletic track , schools,etc.

PU Binder cured with the air humidity, has low viscosity, is solvent free, pu binder combines and bonds sbr or epdm rubber granules ,RIM components, polyurethane granules and sponge particles. Also it can be used as lining for insulation and for pastin

Preparation-Applcation :

It can be used for kids playground, running track , sports ground, walkways and offices .

Moulded in production : Rubber granules and binder are mixed taken into moulds, and then pressure is applied. Rigid parts are obtained like in the form of different types of tiles. After that in the application area, by adding together , the ground is covered, 160 bar pressure , mold temperature of 130 degree gives reasonable result in 12-15mins.In molding application, binder content should not fall below 5% .

One site application:

applied on dry surface, free of materials that might prevent binding . e.g. dust , loose particlesetc (in case of asphalt or concrete ). The success in the application depends on the right preparation of the under lay and use of the materials .

Ratio Mixture :

Recommended : PU Binder : SBR Granules = 1:8 by weight

PU Binder: EPDM Granules=1:6 by weight

Package:

20kg/Barrel, 200kg/ Drum

Storage :

12 Months in unopened original packaging stored in standard room conditions.

Remarks :

The floor must be smooth, dry and clean. Must be removed from oil, rust and burr. Do not add any foreign materials . Concrete humidity should not be above 4%, ambient humidity should be at least 40% and most 80%. To begin the application, must wait for the appropriate humidity. . Working time of PU Binder decreases when ambient temperature rises.

Prolonged storage of partially used containers containing PU Binder must be avoided as contact with atmospheric moisture will result in skinning and clouding of the product.

Caution:

The application must take place in well-aired places using protective gloves. Skin or eye contact must be avoided, otherwise wash carefully with soap and water.
