Chem-Rock DTM (1 Gallon)

Chem-Rock DTM

Description

CHEM-ROCK DTM is a high solid, 2-component, chemical resistant amine adducts cured epoxy mastic primer/finish coating formulated to provide chemical resistance and superior adhesion to a variety of substrates. CHEM-ROCK DTM is designed to bond to marginally prepared steel, concrete, fiberglass and galvanized metal. Accepted for use in USDA/FDA inspected facilities.

Uses

CHEM-ROCK DTM can be used as a direct to metal primer or as a finish coating to provide high corrosion and chemical resistance for steel structures in marine or industrial environments. CHEM-ROCK DTM can also be used as a tank lining primer and finish coat inside tanks holding fresh or chlorinated water, wastewater, gasoline, crude oil, etc.

Typical Coverage

CHEM-ROCK DTM is typically applied at 200 square feet per gallon per coat depending upon substrate and project requirements.

Physical Properties

Limitations & For Best Results

• Can be thinned with up to 20% MEK for easier spraying.
• Do not apply when Humidity exceeds 70% indoors.
• Allow each coat to dry to 'tack-free' prior to recoat.
• When re-coating, always apply the next coat within 24 hours of completing the previous coat.
• This product is batched to order and often requires 7-10 days lead time.

Product Application

Apply by brush and roller or airless sprayer. ROCK-TRED product test data is based on environmental temperatures of 75° F. Viscosity and working time are always affected by temperatures above or below that mark. When applying product always consider the ambient, surface, and product temperature at the time and place of installation.

Colors

CHEM-ROCK DTM is manufactured in White, Light Gray and Dark Gray. Most other ROCK-TRED Standard Colors and some specialty colors are available at additional cost with additional lead time and minimum order quantities. Most ROCK-TRED products are available in a wide range of textures using an appropriate aggregate.

Chemical Resistance

Always refer to ROCK-TRED's chemical resistance chart for specific information on each product / system or contact ROCK-TRED directly.

Product Storage

DO NOT allow ROCK-TRED products to freeze. All ROCK-TRED products should be properly stored above the floor on pallets or shelves, and in an area that has a constant minimum temperature of 50°F.

Surface Preparation

Always apply ROCK-TRED products to a clean / sound substrate that is free of laitance, grease, oils, debris, and curing compounds. Concrete substrates should be cured for a minimum of 28 days prior to application of product [except as otherwise noted on the individual Product Data Sheet]. Whenever possible, remove existing coating systems completely; if complete removal is not possible dull the finish by sanding and always perform tests to determine adhesion and compatibility to the existing substrate. Rusted metal must be prepared to a minimum SSPC-SP2 profile. When applying to galvanized metal a SSPC-SP7 brush blast is recommended. Whenever possible abrasive blasting of metal substrates is preferred. Mechanical preparation by means of a shot-blasting or diamond grinding machine to a minimum CSP-2 profile is the best and recommended preparation method for concrete substrate applications. If the substrate is not properly prepared and the appropriate profile is not achieved, failure of the product to adhere to the substrate may occur.

Clean Up

Application tools and equipment can be cleaned with soap and water immediately after use, or with solvent once the product has begun to cure.

Disposal

Product containers will contain product residue and must be disposed of properly. Label warnings must be observed at all times. All containers must be disposed in accordance with federal, state, and local regulations.

Important Notice

Always read and acquaint yourself with ROCK-TRED's Product Data Sheet, SDS [safety data sheet], and product labels for each individual product prior to mixing and prior to use. For further assistance, product questions, additional information and/or unexpected or unusual installation conditions – contact your Area Sales Representative or ROCK-TRED directly for recommendations. Kit components are pre-measured for optimal performance. Catalyzation errors due to incorrect mixing in the field voids product warranty.
