LIQUID VAT DYES

Founded in 1929 as a chemical manufacturer in East Rutherford, NJ. Primary products were:

Sodium Hydrosulfite

Sodium Formaldehyde Sulfoxylate

Zinc Formaldehyde Sulfoxylate.

Diversified into other industries in 70s:

Manufacturing Zinc Oxide from Zinc Carbonate by-products

Built a Zinc powder plant for captive use and alkaline battery market.

Purchased Passaic Color and Chemicals in order to expand into the dye business serving Textiles, Plastics, Paper, and Leather markets.

Started plastics reprocessing and compounding business

INVESTING IN OUR FUTURE FOR 82 YEARS

Started to exit the manufacture of old line

products in US:

Sold our Hydrosulfite plant to Virginia Chemicals, division of

Celanese.

Sold our Zinc powder business to Noranda Corporation.

Developing new technologies:

Started manufacturing micronized waxes for ink, coatings, and

plastics industries.

Started manufacturing Color Concentrates for Plastics industry.

Formed Royce International with a focus towards Asia.

Increased emphasis on development of new products using

reductive chemistry.

STRATEGY SHIFT FOR THE FUTURE

Initiated raw material sourcing from Mainland China and India in 1970s.

Developed close manufacturing partnerships with chemical plants in China

and India.

Transferred technology to manufacture products to meet Global quality

standards.

1n 1996, established a Technical Center in Tianjin, China to support quality

control and interface with manufacturers.

In 2009, formed RP International, a JV with Palmer International to

manufacture amine curing agents.

1n 2011, started a JV plant for manufacture of RoyceVAT Liquid Dyes in

China.

In 2012, major capacity expansion at Skippack plant to be completed by

June.

In 2012, acquisition of an industrial property in Gaffney, SC.

Continuing to build on our strengths in Asia, through manufacturing

partnerships, technology transfers and joint ventures.

We continue to maintain a dominate position in our markets by

manufacturing products in the US and Asia.

Sino – Royce Technology Co., LTD is pleased to announce the launch of its Roycevat Liquid Dye line. Building on over 80 years of experience, the Roycevat line of Liquid Vat dyes are globally recognized as the highest quality, most sought after products for use in dyeing of cotton and cotton-blended fibers.

It is Royce’s unique ability to produce Liquid Vat dyes at high concentrations that separates us from the competition. Today, Roycevat Liquid Dyes command 70% of the US Market.

LIQUID VAT DYES

8

Roycevat Liquid Dyes are used in the U.S.A. at all continuous dye and printing houses.

The U.S.A. market is producing high-end technical textiles.

99% of all U.S.A. dyehouses exclusively consume Vat dye liquids.

U.S.A. dyed fabric is globally considered the benchmark for quality.

LIQUID VAT DYES – CURRENT MARKET U.S.A

9

Roycevat Liquid Dyes, generate only 25% of the

wastewater normally generated by traditional Vat Dye Powders. And, this wastewater is readily biodegradable, therefore the dyeing mill's pollution treatment costs are much lower.

Roycevat Liquid Dyes reduce employee exposure to dust,

and improve factory environment.

Roycevat Liquid Dyes are commonly used with automatic dispensing systems. This significantly improves dyeing consistency and limits employee exposure in the dyeing factory.

Environmentally Friendly

10

Roycevat Liquid Dyes are ground and filtered to a

specification of 97% <1 micron, and 100% <3 microns. Because of this very small particle, the dye is bonded with the fabric stronger, so the yield and wash-fastness are improved. Therefore less unfixed dye remains in the waste water for treatment.

Roycevat Liquid Dyes require up to 50% less sodium

hydrosulfite and caustic than typical vat dye powders.

Roycevat Liquid Dyes contain very little dispersing agent,

and require much less dispersing agent during the dyeing process. This saves costs, and greatly improves the quality of the wastewater.

Environmentally Friendly

Environmentally Friendly

Vat Dye Powder Liquid

Vat Dye Powders exhibit 5 times more bleed-off in the chem-pad than Roycevat Liquids

12

Roycevat Liquid Dyes are ground and filtered to a

specification of 97% <1 micron, and 100% <3 microns, which make the yield improved and the shade purer.

Roycevat Liquid Dyes have extremely good dispersion, therefore dyeings are typically more even and the cloth is better penetrated.

Roycevat Liquid Dyes are easily dispersible, there is little or no loss of product in the mix tank. Traditional Vat Dye Powders do not easily disperse leading to losses of up to 60%, and inconsistency of product strength and shade.

SUPERIOR PERFORMANCE

13

Roycevat Liquid Dyes are standardized using extremely

tight tolerances for total color difference. This greatly

improves dyeing mills production quality.

Roycevat Liquid Dyes are standardized both on cotton and

polyester – this improves the consistency of polyester

dyeing.

Roycevat Liquid Dyes can be finely filtered; this decreases

the problem of specking on dyed cloth.

SUPERIOR PERFORMANCE

14

Benefits for Continuous Dyeing

Royce currently supplies Roycevat Liquid Dyes to all U.S. continuous dye houses.

Our Customers choose Roycevat Liquid Dyes because they allow them to achieve darker shades using less dye.

Roycevat Liquid Dyes penetrate the fabric better, and this leads to greatly improved wash fastness.

Roycevat Liquid Dyes migrate less because of the very small particle size. This greatly improves side-center-side shading, and gives better color control.

15

Benefits for Vat Dye Printing

Roycevat Liquid Dyes are being used to print upholstery, camouflage and outdoor fabrics.

In camouflage printing Roycevat Liquid Dyes

have been formulated to emit the target I.R. reflectance.

Roycevat Liquid Dyes eliminate the need for the dyeing mill to dissolve the vat powder therefore they are more efficient and consistent.

16

Benefits for Vat Dye Printing

Roycevat Liquid Dyes are formulated with consistent viscosity therefore printing paste quality has little variation.

This Consistency leads to better control of penetration and less bleed through.

The print paste will have less of a tendency to dry out. This is because of our special formula.
