DESCRIPTION
BIO-SEAL was formulated to provide safe and effective sealing and reinforcement of surfaces such as concrete exposed to contamination from road salts, gasoline, oil drips and similar materials. The unique BIO-SEAL formulation has excellent tolerance to the dampness left in concrete after preparation for coating by high pressure water jetting. The formulation is solvent-free to avoid the objectionable odour and explosion hazards of epoxy solvents. Absence of solvents also assures compliance with all present and proposed air pollution regulations. BIO-SEAL is non-blushing and can be applied and will cure underwater.

USES
SURFACE REINFORCEMENT An ideal binder for making concrete repair mortar. A standard 2 gallons (7.5 litres) kit of BIO-SEAL will accept 2 gallons (7.5 litres) of sand filler to yield 4 gallons (15 litres) of a 'self-leveling' filler or up to 3 gallons (11 litres) of sand filler to yield 5 gallons (18.75 litres) of a trowelable mortar.

REINFORCEMENT Used extensively in glass reinforced epoxy systems especially for applications such as underwater hull repair and custom GRP fabrications. The long potlife, predictable cure rate and total absence of surface 'blush' together with excellent physical and chemical resistance make BIO-SEAL ideal for applications exposed to harsh industrial or marine conditions. Because of the chemical curing process and relatively gentle exotherm, unlimited applications may be made at one time.

SEALER When used as a sealer BIO-SEAL is designed to be absorbed into the concrete surface, very heavy applications will result in a glossy, slippery film which can be made skid resistant by broadcasting sand into it while still liquid.

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. Conventional abrasive blasting using air/abrasive or centrifugal blasters are preferred methods of surface preparation in most cases where oily or greasy contamination is a problem.

APPLICATION
Mix BIO-SEAL epoxy base with the BIO-SEAL curing agent supplied. Use a mechanical mixer if possible to ensure thorough mixing. The mixing ratio is 3/2 (base/curing agent) by volume. BIO-SEAL does not require a 'sweat-in' or induction time and the mixed components should be used immediately.

Potlife is approximately 40 minutes at 77 degrees F (27 degrees C), small amounts of solvent may be added if the mixture begins to thicken noticeably towards the end of its working life. Apply in a thin film using a brush, roller, pad or squeegee. Overcoating with IES-251, BIO-DUR or other IES materials may be carried out before full curing of the BIO-SEAL if necessary since chemical curing will continue normally even when overcoated.

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

TRANSPORTATION
USDOT, IATA & IMO "Non-Regulated"
