Why Use KIRASOL Products?The KIRASOL family of products will rapidly, and safely remove difficult organic contaminants including oils, heavy hydrocarbons, asphalts, asphaltenes, waxes, adhesives, pitch, oil-based inks, lubricants, and polymeric binders.

Ease of Use Quicker and more effective cleaning Non-caustic and non-corrosive safe for equipment and workers Versatile Dilutable with water (typical use concentration 1%-10%). Wash away easily.

Ease of Disposal Biodegradable Mild pHs (No waste stream neutralization) Non-chlorine containing Organic contaminants in most cases will separate from KIRASOL products assisting in waste management and minimization.

Why is KIRASOL Effective?1. Penetration 2. Emulsification and removal 3. Separation

Why Use NOXOL Products?The NOXOL family of products will rapidly, and safely remove inorganic contaminants including difficult metal oxides and salts.

Ease of Use Versatile, remove difficult scales, used in aqueous environment Fast working (High throughput) Equipment safe, non-corrosive to metal and other substrates Worker safe, non-corrosive, non-flammable and non-volatile Mild pHs

Ease of Disposal Biodegradable Mild pHs Non chlorine containing

What are NOXOL Products?Advanced compounds that remove mixed oxides, difficult salts and water hardness scales. This family of products will rapidly and selectively remove corrosion products and scale from surfaces selectively without Metal ions corroding the underlying material.
