DESCRIPTION

CORRO-DUR 568 is unique material based on proven technology found in the related CORRO-DUR products CORRO-DUR 252 and CORRO-DUR 561.

CORRO-DUR 252 is an extremely smooth, low surface energy (non-stick) coating manufactured for applications such as surfacing assembly tables subjected to repeated sliding from items such as cardboard boxes and filled paper bags. The proprietary non-stick ingredients provide permanent lubrication which minimizes wear and allows easy sliding.

CORRO-DUR 561 is a surface tolerant, Kevlar™ reinforced epoxy coating which has found wide use in fields as diverse as underwater applied anticorrosive coating to lining in nuclear plant exposed to high radiation. The product is very 'field friendly ' and the cured film is extremely tough and durable in service.

CORRO-DUR 568 was created using the particular attributes of each of the above products to produce an extremely tough and surface tolerant material with the low surface energy ingredients necessary to promote easy contaminant release and a sliding rather than gouging action when subjected to heavy loads.

Lab trials of cured material have shown excellent resistance to heavy scratching with sharp, flinty pebbles which would heave gouged similar unreinforced and unmodified materials. Application to compromised surfaces even underwater remains as easily accomplished as it is with the original CORRO-DUR 561.

SAFETY INFORMATION

SURFACE PREPARATION

Remove surface contamination by high pressure water jetting or similar methods with or without abrasive injection. Hand held power tools such as grinders or needle guns will give good results if applied conscientiously in small areas but will be inadequate in large areas. Plan to apply the CORRO-DUR 568 before recontamination of the prepared surface which can interfere with adhesion. Conventional abrasive blasting using air / abrasive or centrifugal blasters are preferred methods of surface preparation in most cases where oily or greasy contamination is not a problem. In cases where deep contamination is present from previous service cleaning using a high pressure purified water/sodium bicarbonate system is recommended.

MIXING PROCEDURE

CORRO-DUR 568 is supplied in 1.9 gallon (7.2 liter) kits of 1 gallon of epoxy base and .9 gallons of curing agent. Thoroughly mix the base and the curing agent until completely blended. Mixing is easily accomplished by folding the components into each other using a spatula or piece of wood. Once mixing begins there will be about 40 minutes of working time available at 80°F (27°C). This time can be extended by keeping the components and mixture cool.

APPLICATION

CORRO-DUR 568 may be applied using a trowel or 'pool float' devices at film thickness of 20-40 mils (.5-1mm). When coating rough steel it is recommended to apply two (2) coats in order to assure proper coating of sharp edges or other irregularities.

TEMPERATURE

Temperature exerts a considerable influence on the rate of hardening of chemically cured materials such as CORRO-DUR 568 . In broad terms expect each 18°F, (10°C) rise or fall in temperature to half or double dry times and pot lives.

CORRO-DUR 568 may be applied in temperatures as low as 45°F (7°C) - curing will be slow, however the viscosity of the material will still be workable.
