Bio-Tuff 592
BIO-TUFF™ 592 is a solvent-free, toughened, chemically resistant coating. When fully cured it is hard, yet extremely flexible.
BIO-TUFF™ 592 is an extremely adhesive coating suitable for application over primed or painted steel or concrete. The formula is designed to be uniquely abrasion and impact resistant.
BIO-CHIME™ 390 is designed for applications where a flexible, corrosion resistant coating is required. It is especially recommended for exposure to aromatic and aliphatic hydrocarbons, mineral acids, esters and alcohols except methanol.
Designed for applications where resistance to aggressive chemicals is needed together with ability to resist impact and abrasion damage.

SURFACE PREPARATION:
This may be accomplished in several ways:
New Concrete: leave to cure properly for a minimum of 20 days before coating. Weak surface laitance must be removed by either; acid etching or abrasive blasting. (Note: acid etching can be difficult and unreliable unless performed with particular attention to proper acid application, scrubbing, rinsing, and drying.) Abrasive blasting, (recommended), may be effected by conventional open blasting or with “Blastrac”® type centrifugal equipment. The concrete surface after preparation should have the granular appearance of medium sandpaper.
Aged Concrete: best prepared by abrasive blasting. If contaminated, contact Thin Film Technology, Inc. for advice.
Steel: Abrasive blast or power tool clean for atmospheric service.
Existing Coatings: May be applied over clean coatings in good condition, abrade existing aged coatings before overcoating with BIO-TUFF 592. Do not overcoat with conventional coatings.
APPLICATION:
Follow the procedure described below:
Apply by heated, plural component airless spray for best results, small areas can be applied by brush or spreader.
