IOTA 6289 Methyl Silicone Resin for Concrete and Stone

Product Description:

IOTA 6289 is a polymer of polymethyl alkyl-functionalized silicone resin with low viscosity.

When incorporated into cement-based formulations, it disperses in aqueous slurry.

Its addition reaction imparts hydrophobicity and significantly reduces water uptake.

During cement curing, the alkoxy and methyl silane groups react with cement hydrates.

It is suitable for applications requiring protection against liquid water penetration into substrates.

Technical Specifications:

Item	Specification
Appearance	Colorless transparent liquid (clear to pale yellow)
Content (%)	>96
Viscosity (mm²/s)	30–50

Composition:

Silicone resin

Alkyl silane reactive components

Advantages (as cement matrix additive):

1. Reduces capillary water absorption.

2. Minimizes issues such as efflorescence caused by water ingress and soluble salt migration.

3. Lowers VOC release during reaction.

Applications:

1. Low-viscosity fluid for cementitious mixtures.

2. Provides water repellency within chemically reactive cement matrices.

3. Improves overall hydrophobicity of cement-based materials.

4. Acts as an additive to enhance water resistance of cement-based construction materials.

5. Functions as a hydrophobic agent for integral waterproofing of cement-based materials.

Directions for Use:

Dilute before application.

1. For use as an internal additive in concrete: optimum dosage is 0.1%–0.5% by weight.

2. For surface waterproofing of stone or concrete: dilute with alcohol solvent to 5%–10% concentration and apply by spraying or brushing. Cure at ambient temperature under moist conditions to form a durable waterproof film.

Packaging and Storage:

1. Packed in 20 kg, 190 kg, or 1000 kg drums; custom packaging available.

2. Store unopened in original container below 32 °C (90 °F) in a dry location. Avoid direct sunlight, contact with alkaline materials, and high temperatures.

3. Shelf life: 18 months under recommended storage conditions.
