EIFS / ETICS

An Exterior Insulation Finishing System (EIFS), also known as EWI (Exterior Wall Insulation Systems) or External Thermal Insulation Composite Systems (ETICS) is a type of cladding system that provides exterior walls with an insulated finished surface and waterproofing in an integrated composite material system. Put another way, an Exterior Insulation Finishing System / External Thermal Insulation Composite Systems can be defined as an ideal energy efficient thermal wrapping or facade insulation applied to the exterior surfaces of a building which is then finished with a long-life, decorative and protective wall coating that can be installed on any type of construction. 

In the construction industry, there are a number of versions of EIFS / ETICS. The most basic and common EIFS / ETICS is called a barrier EIFS, also known as traditional or conventional EIFS / ETICS, which is applied to a solid wall (brickwork, blockwork, pre-cast panels and the like). Another type is called EIFS / ETICS with drainage, which is a barrier EIFS / ETICS to which a water drainage capability has been added. This is done mainly for wood structures.

It is recommended to use our SLEO HPMC MHEC products in EIFS applications to improve processability and enhance bond strength. Our SLEO RDP products are also widely used in EIFS to enhance adhesion and cohesion, increase flexibility and impact resistance, improve surface abrasion resistance, and avoid crack and lump formation.

The Role of SLEO cellulose and RDP in EIFS / ETICS:

●Improved adhesive strength and flexibility: SLEO cellulose and RDP have good thickening performance and lubricity, which can improved the adhesive strength and flexibility of EIFS adhesive.

●Enhanced water retention and extended working time: SLEO cellulose and RDP  substantially reduce the loss of water into absorbing substrates in formulations. The water retention ability of cellulose also strongly enhances the adhesion strength of EIFS adhesives. This is because the binders have enough time for hydration and at the same time do not lose water.

●Optimized product consistency and rheology: SLEO cellulose and RDP  are vital key to adjust suitable consistency in fresh mortars. Suitable consistency enables fresh plaster to attach well on walls as well as to make surfaces smooth and be applied easily without the feeling of stickiness. The aqueous solution of cellulose is a non-Newtonian system, and the properties of its solution are called thixotropy.

●Improved hydrophobicity: After add the SLEO cellulose and RDP , the hydrophobicity of EIFS have improved, waterproofing effect is significantly increased.

●Improved workability: Better leveling and reduced stickiness of SLEO cellulose and RDP can be applied easily to EIFS adhesives, which easy to operate and construction, and can significantly improve the construction efficiency.

●Improve coating performance with excellent early strength: cellulose combine the cohesion of polymer materials and the durability of inorganic materials. They can ensure the early strength of the mortar and other essential properties needed to EIFS and new construction.

●Good water resistance, good compatibility with general products: cellulose substantially reduces the loss of water into absorbing substrates in formulations. The water retention ability of cellulose also strongly enhances the adhesion strength of EIFS adhesives. This is because the binders have enough time for hydration and at the same time do not lose water.

●Exhibit high strength, strong adhesion, and alkali resistance: cellulose has good retention, thickening property, Stable chemical properties effectively resist alkali attack.
