Stanrose® Chemiseal CRS  (Ultimate Chemical Resistance System)                                 
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Description : Stanrose® Chemiseal CRS is a coating / topping / lining designed for use where chemical resistance is required on concrete or steel substrates. As the protective component of a system, it is used in conjunction with Stanrose® Primer, a two-component epoxy primer providing excellent adhesion to dry or damp concrete substrates and good chemical-resistance. Stanrose® Chemiseal CRS is based upon a modified Stanrose® Vinyl Ester polymer resin that provides a hard and durable surface. It offers high resistance to a variety of solvents, acids and oxidizing substances and excellent dry heat-resistance up to 140^o C  (284^o F).
It is specially designed to serve the needs of the new age industry. It is an economical system, high chemical resistance, high impact resistance, aesthetically appealing which can be applied in less than half the time required for conventional lining. It costs half as much and has a life span comparable to the most sophisticated lining system. Like all composite Stanrose® Chemiseal CRS combines the good qualities of its various ingredients to give a system that is much superior to its constituents. Thus Stanrose® Chemiseal CRS has a much better resistance to chemicals particularly oxidizing agents and high concentration of alkalies than epoxies and a better adhesion to concrete than FRP and Furan linings.

Where to Use ?
● As a smooth, chemical-resistant lining on concrete or steel substrates.
● As a broadcast, textured floor system to provide a slip-resistant, durable wearing surface in pedestrian areas where aggressive chemicals are present.
● Protection of containment tanks, machine bases, and plant floors and walls exposed to aggressive chemicals.
● Protection against ground-water contamination resulting from uncontained chemical spills.

Application of Stanrose® Chemiseal CRS :

Concrete Substrates :

● Smooth Coating : This provides a smooth, easy-to-maintain system.
● Primer Coat : Apply Stanrose® Primer onto concrete substrate using a brush, roller or squeegee to a uniform coverage without ponding. Allow primer to cure for a minimum of 6 hours at 20^o C (68^o F) or 10 hours at 10^o C (50^o F)
● Screed Coat : Apply Stanrose® Screed for a minimum of 12 hours.
● Applying of one layer of 450 gsm FIBER mat and pigmented with high chemical resistant resin.
● Applying of 2 coats of Vinyl Ester Resin based Fiber Reinforced -- Stanrose® Chemiseal CRS as finish coats using a brush, roller or squeegee to a uniform coverage without ponding and let it cure for 36 hrs.

Steel Substrates :

● Consolidation and sealing of common steel substrates with Stanrose® Primer is not usually required under typical circumstances. However, due to variations in steel quality, surface condition, surface preparation and ambient conditions, reference test areas are recommended to determine whether priming is required to prevent the possibility of de-bonding, blisters, pin-holes or other defects.

● Application of Stanrose® Chemiseal CRS over properly-prepared steel surfaces is typically the same procedure as outlined above for both Smooth Coating and Broadcast Build up Systems over concrete substrates, excluding the use of Stanrose® Primer, unless a thicker wear coarse layer is required to resist heavy traffic.

Advantages :
● Stanrose® Chemiseal CRS may be applied as a smooth coating system or as a build-up system incorporating aggregate.
● Both systems are suitable for vertical and horizontal surfaces.
● The build-up system provides a hard-wearing and slip-resistant floor finish.
● Exhibits excellent impact-, abrasion- and fatigue-resistance. 
● The systems both provide excellent protection for steel and concrete against a wide range of chemicals.

Limitations :
● Stanrose® Chemiseal CRS, as a primary or secondary containment system, is best installed by skilled and experienced applicators.
● As a Vinyl Ester, this material does not bond well to damp substrates. It must be applied over a surface primed with Stanrose Primer as recommended
● Minimum/Maximum ambient and substrate temperature: 15°C/30°C (59°F/86°F).
● Substrate temperature must be at least 3°C (5.5°F) above the measured dew point.
● Do not apply onto porous surfaces where moisture vapour transmission will occur during application.
● Maximum relative humidity during application and cure: 85%.
● Do not hand-mix Stanrose® Chemiseal CRS; mechanically-mix only.
● It is very important to provide efficient ventilation to prevent Stanrose® Chemiseal CRS fumes from remaining in the coated area, as this will inhibit proper cure. Ventilation should be provided during application and during the entire cure period.
● Minimum wet film thickness per coat of 10 mils as recommended in the application section;
● Due care should be exercised in applying the system as it is flammable.
● Protect from dampness, condensation and water-contact during the initial 24-hour cure period;
● Stanrose® Chemiseal CRS is not suitable for use on exterior, slab-on-grade concrete substrates.
● While the material is supplied in colours, it is not intended and should not be used as a decorative finish, but as a chemical resistant barrier. In addition to discolouration due to ultraviolet light, exposure to some chemicals may result in a change in the appearance of the finish, with loss of gloss values, change in colour and or staining. This however, does not necessarily constitute a compromise of this protective surfacing
