INTRODUCTION OF PAINT DETACKIFICATION

What is Paint Detackification? A Program that be used to treat paint overspray from

water circulation for painting booth.

A Detackification program should have the capability to provide:

Good detackified sludge

Less order from the water

High sludge removal efficiency

Clean recirculating booth water

High sludge solids and low sludge volume

Low corrosion rate

Better foam control (less emission)

Microbial control (safety)

The typical Paint Detackification Program consists of 5 chemical products that each serves a specific function:

Detackifier D2430S

Reduce or eliminate paint tackiness

Coagulation of paint solids

Flocculant - D2402

Agglomerate suspended paint solids

Enhance paint sludge removal from the process

Improve dewatering of sludge

pH adjuster

Ensure water is in condition to properly detackify paint solids

Minimize corrosion rate

Additive

Oxidize the solvents to eliminate smell

Biocide

Control bacteria levels

Minimize corrosion

Without Treatment Detackification Flocculation

Bad Treatment

Good Treatment

PARAMETERS OF SLUDGE PAINT TREATMENT SYSTEM

Cutomer Goals

Automotive manufacturers are looking for products with improved performance while seeking to reduce overall system cost Lower suspended solids returning back to spray booths Simplify the paint spray booth process to reduce capital investment Reduce energy and cleaning costs

Auto industry as a whole is striving for more environmentally responsible solutions Conserve non-renewable resources Minimize carbon footprint Reduce waste Non smell spread

OEMs desire less complexity in the manufacturing process Ease of operation Process flexibility

Vision & Goals

Vision & Goals

Customer Benefits

Positive environmental impact Reduce carbon foot print from other chemical contribution Reduced daily wastewater treatment impact Conservation of water Decreased land fill volume

Superior product performance Improved sludge removal efficiency Reduced sludge settling Fewer paint solids returned to paint spray booths Cleaner booth water Decreased foam formation (due to bio-adhesive properties) Lower total dissolved solids and corrosion tendency Longer booth water life

Greater ease of operation and process flexibility Wider operating window (less pH sensitive, less foam formation) Decreased paint spray booth maintenance (lower suspended solids) Effective treatment vs. solvent borne/waterborne. Proven pour over transition

Lower overall system costs Reduced paint spray booth maintenance, chemical, wastewater treatment, and

disposal costs

Experience with all sludge system designs

Not only with good chemical programs, but knowing how in

application is the turn key for success

Capability to assist and/or advise for the design of the most efficient system

to:

Lower the chemical cost

Minimize labor intensity

Maximize system performance

VALUE PROPOSITION - SYSTEM DESIGN

Are main distributor for TOTAL and Chemetall products in Vietnam.

Capability to treat all types of paints from PPG, DuPont, BASF, Nippon, Kansai, Rohm & Haas, etc.

Low to high solids

Solventborne

Waterborne

Purge solvents

Cleaning solvents
