TUFF-POXY Primer #1

Product Description

TUFF-POXY PRIMER #1 is a 2 component, 100% solids, solvent-free liquid applied, epoxy-polyamine primer. The special polyamine gives unique penetrating characteristics and a rapid cure. It has low viscosity and excellent adhesion to various surfaces and basecoats.

General Information

Basic Uses: TUFF-POXY PRIMER #1 is an epoxypolyamine primer used in the TUFFLEX Decking Systems and other specialty systems. It is specifically formulated to improve polyurethane elastomeric membrane adhesion to concrete and plywood. Because it has low odor, TUFF-POXY PRIMER #1 is excellent for indoor applications.

Limitations: Once the material is mixed together, it must be used within 15 to 20 minutes since TUFF-POXY PRIMER #1 has a short work life and cures and solidifies rapidly when the 2 parts interact. Opened containers must be sealed tightly and remaining unmixed material must be used within several days. Surfaces to be coated must be properly prepared, dry, clean, and free of all foreign matter.

Colors: Side-A: Clear & Side-B: Light Yellow

Packaging: TUFF-POXY PRIMER #1 is packaged in kit form. The VOLUME MIXING ratio is 2 parts Side-A to 1 part Side-B (Side-A / Side-B = 2:1).

Sizes: TUFF-POXY PRIMER #1 is available in kits of three quarts, three gallons, three 5 gallon pails.

Product Installation

Surface Requirements: Successful bonding required structurally sound, strong and clean substrates. The substrates must be cleaned to ensure that it is free of all oils, “laitances”, greases and other contaminations, such as concrete curing compounds, that may cause poor adhesion of TUFF-POXY PRIMER #1. After cleaning, the surfaces should be rinsed thoroughly to remove loose particles and dust created during shot-blasting or grinding and traces of the cleaning chemicals. Primers, adhesives, detailing, membranes, etc. should not be applied until the surface is dry.

Mixing Instructions: This primer may be diluted with Xylene or Toluene, to the extent allowed by local Air Quality Management authority. Addition of solvent extends the work life of the mixture, provides better surface penetration and is economical. However, strict fire fighting precautions (equipment, procedures, etc.) and health precautions must be observed. TUFF-POXY PRIMER #1 Side-A and Side-B should be thoroughly agitated prior to mixing to ensure a homogeneous material. TUFF-POXY PRIMER #1 must always be mixed with a two parts Side-A and one part Side-B (Side-A: Side-B = 2:1). The combined components should be thoroughly mixed for at least 3 minutes, if mixed by hand.

Optional: If odor or the use of flammable solvents is not a concern. You may add small amounts of solvent as desired to meet local VOC laws. Blend with a mechanical mixer (explosion proof) for 3 minutes. Induction time is not required.

Application: TUFF-POXY PRIMER #1 should be applied at the rate of 1 gallon/350 square feet. It can be applied using a brush or phenolic core roller.

Curing: Allow TUFF-POXY PRIMER #1 to become tacky to the touch, a minimum of 3 hours at 77ºF., before filling cracks, joints, or applying the coating.
Note: Temperature will affect the curing time of TUFF-POXY PRIMER #1. Higher temperatures will significantly accelerate the cure time while colder temperatures will significantly retard the cure time. To improve cure/bond time in cooler temperatures, TUFF-POXY PRIMER #1 may be pre-mixed and allowed to sit in the container for 10 to 15 minutes (the cooler the temperature, the longer the residence times) before application. In hot temperatures, the pot life of TUFF-POXY PRIMER #1 is reduced therefore the residence time should be kept relatively short. Recommended application temperature is > 10ºC (50ºF).

Equipment Cleanup: Equipment should be cleaned immediately after use with an environmentally-safe solvent, as permitted under local regulations. The primer is difficult to remove after it has cured.
