Chemolac 1000

Chemolac 1000 is a strong high performance chemical chemical-resistant novolac epoxy system.

Product Description

Chemolac 1000 is a three-component, self-leveling, novolac epoxy with outstanding chemical resistance. Chemolac 1000 can be applied directly on the primed substrates as a high performance topcoat.

Applications

Chemolac 1000 is specially formulated for highly aggressive chemical environments • For use on concrete, cementitious mortar, epoxy mortar, and steel substrates. • For protective lining of storage tanks, ETP, silos, and bund areas
As an anti-corrosion coating in food and beverage processing plants, sewage treatment plants, chemical and pharmaceutical plants, bottling plants, etc.

Salient Features

Outstanding Resistance to many chemicals, acids, and alkalis.
Excellent self-leveling and anti-sag properties
Superior Adhesion to Concrete and Steel
Outstanding Mechanical Strength and Abrasion Resistance

Method of Application

All Chemsol Products are recommended to be applied only by Approved Applicators and should be handled after using proper PPEs like Gloves, mask, goggles, etc.

Application conditions

Note: The substrate temperature must be at least 30C above the prevalent dew point temperature to reduce chances of condensation on the floor.

Substrate Quality

The concrete substrate must be sound and of sufficient compressive strength (minimum 200 Kg/cm2) with a minimum pull-off strength of 15 Kg/cm2. The substrate must be clean, dry, and free of all contaminants such as dirt, oil, grease, coatings, surface treatments, etc. If required, apply a test area first.

Substrate Preparation

Substrate must be prepared mechanically using abrasive blast cleaning, Scarifying or grinding equipment to remove cement laitance, rust, and achieve an open Textured surface. Remove weak concrete and expose surface defects such as blowholes and voids. Repairs to the substrate, filling of blowholes/voids, and surface levelling must be carried out using appropriate products. Ensure that the dust, loose and friable material is completely removed from all surfaces by brush and vacuum before application of the product. The substrate has to be primed or levelled with Chembase 150 in order to achieve an even surface. Allow the primer to cure for 5-6 hours. After this, apply a coat of Chemolac 1000 with a notch trowel.

Mixing

Stir the resin part mechanically. Add colour paste into resin and mix until a uniform colour is achieved. Add hardener to this mixture and stir continuously for 2 minutes with a motorised paint stirrer until a uniform mix has been obtained. After this, add the aggregates and continue mixing for an additional 1 min. Overmixing must be avoided to minimise air entrainment.

Note that the mixture has a stipulated pot life hence the application should immediately commence after mixing the contents.

Curing Schedule

The epoxy curing reaction rate is temperature dependent. Refer the following table to know how quickly the floor can be brought to service

Temp. (°C)	Foot traffic	Full cure
10°C	48 hours	120 hours
20°C	36 hours	96 hours
30°C	24 hours	72 hours

Cleaning of Tools

Clean all tools and application equipment with thinner EP140 immediately after use. Hardened and/or cured material can only be removed mechanically.

Packing

Chemolac 1000 is available in a pre-weighed kit which covers a 10-12 sq m area with an approximate thickness of 1mm

Storage conditions

Store in a dry and covered shed between 5 °C to 30 °C, away from sources of heat and naked flame.

Handling & Safety

Keep the containers tightly sealed when not in use. Avoid skin contact and inhalation of fumes (if any). While spraying, it is advised to wear a mask. If it comes in contact with the body, wash affected parts with plenty of water. In case of persistent irritation, contact a physician.
