DUOGARD® II
Water-Base Form Release Agent

DESCRIPTION
DUOGARD II Form Release Agent is composed of organic chemicals emulsified in water which react with the alkali content of concrete to form a release film that effectively prevents the bonding of the concrete to the form. In addition, the product also contains a high molecular weight, non-reactive, chemically inert ingredient to assist in clean, quick form release and removal. This exclusive combination of physical and chemical reactive components provides a doubly effective separation... DUO... and the ultimate in form release efficiency. DUOGARD II meets maximum VOC content limits of 450 g/L for Form Release Compounds as required by the U.S. EPA Architectural Coatings Rule.

USES
DUOGARD II Form Release Agent can be used on various types of forms (wood, steel, as well as fiberglass, aluminum and fiber tubes). DUOGARD II increases the life of wood forms by penetrating into the wood to waterproof and prevent deterioration. It reduces maintenance requirements on metal forms because it forms a rustproof film that makes the metal form essentially self-cleaning and rust-free.

DUOGARD II should be applied to fiber tube forms even though they may be pre-coated. Tubes will strip much easier, even 60 to 90 days later. If tubes are stripped in 5 to 10 days, hand rubbing is greatly facilitated when tubes are coated with DUOGARD II.

DUOGARD II cuts machine cleanup time and minimizes concrete build-up. Pavers, trucks, mixers, spreader-finishers, buggies, chutes, and other types of equipment should be sprayed daily.

DUOGARD II can be applied on forms for prestressed and precast concrete to produce a better and cleaner cast. The product will not stain or discolor concrete.

FEATURES / BENEFITS

  • Can be safely used inside or outside.
  • Produces a better and cleaner cast when applied on prestressed and precast concrete forms.
  • Cuts stripping time to an absolute minimum.
  • Reduces form cleaning and repairing.
  • Increases wood form life...prevents rust...and rustproofs metal forms.
  • Effectively minimizes concrete buildup on pavers, R/M trucks, mixers, spreader-finishers, buggies, chutes and other equipment.
  • Prevents bonding between poured concrete and the form.
  • Breaks concrete bond between surface and form cleanly and effectively...leaves smooth surface.
  • Will not stain or discolor concrete and can be painted over.
  • Ready-to-use...requires no additional mixing.
  • Minimizes surface voids.
  • VOC compliant...actual VOC content is less than 100g/L.

APPLICATION
Surface Preparation...Form surfaces are to be thoroughly cleaned prior to application. All rust, scale and previously used form release agents must be removed in accordance with good concrete practices.

Method of Application...Spraying is the ideal method of application... Use a Chapin 8001 spray tip that produces a flow of 1/10 of one gallon per minute. DUOGARD II may also be applied by roller coating, mopping or brushing. A thin film should be applied for maximum economy and efficiency. Runs or puddles need to be brushed out. For metal forms, the best results are obtained with a spray-on "fog" application of DUOGARD II.

Clean up...Tools and equipment used to apply DUOGARD II clean up easily with soap and water.

Coverage...600 to 1,500 sq. ft./gal. (14.73 to 36.82 sq.m./L), depending on the type and porosity of the form surface.
The following coverage rates are approximate:
Form Surface sq. ft./gal.
Hard & Smooth 1,500 (approx.)
Pre-Oil Plywood 1,000 (approx.)
Untreated Plywood  600 (approx.) 

PRECAUTIONS
KEEP FROM FREEZING. DO NOT OVER-APPLY DUOGARD II TO FORMS AND EQUIPMENT. DO NOT DILUTE. Surface tnesions of certain plastic forms may prevent adequate "wet-out" of DUOGARD II. A small test patch application is recommended to ensure uniform coverage of DUOGARD II.

HEALTH HAZARDS
Direct contact may cause mild to moderate irritation of the skin and eyes. Refer to Material Safety Data Sheet for complete health and safety information.
