HOW DOES GUARD DO IT
From our very beginnings we have always been committed to manufacturing innovative, high-quality products, this is done through continuous heavy investment in research and development. We are genuinely concerned about threats to the environment, so we design products to a strict specification in order to be people-friendly and planet-friendly.
Innovative chemical structure
ProtectGuard® products’ unique properties come from their very original chemical structure, which in turn gives the oil and water repellent properties, with a high resistance to abrasion.
ProtectGuard® products are fluorinated acrylic copolymers, which contain four chemical attachments, each one having a specific function:
The fluorinated group.
These are the fluorine atoms, which, by reducing the surface tension of the treated material, create a real barrier that avoids water and oil penetration (and inks as far as graffiti is concerned).
The cationic group.
Allows solubility of the copolymer resin in water and a good link with the mineral substrate.
The non-ionic group.
It is necessary for the product’s use and assist in the fluorinated chains to be distributed on a material surface.
The silanated group.
This reinforces the copolymer adhesion in the fabric of a materials surface which in turn improves then the abrasion resistance and the treatment duration.
Products Respectful of Materials
A completely invisible protection
ProtectGuard® products are impregnation products. They penetrate into materials without forming a film. Invisible once dry, they do not modify a materials structure or its color.
Materials protected with ProtectGuard® products remain permeable to air and water vapour
ProtectGuard® products do not modify the materials characteristics. The permeability loss of moisture for a treated material is less than 10% (result calculated in accordance with the 52615 standard).
TECHNOLOGY OF PROTECTION PRODUCTS
There are 3 main ways to protect materials
Non Film Forming
Permeable to air and water
Not prone to spaling or blistering
Will not impact slip rating
Pores Filling Products
Very good protection against water and dirt
Decreases breathability of the material
Prone to changing the slip rating of the product
Increased risk of spaling or blistering
Good protection against water
Good resistance to chemical products
Form a film
Modify stones appearance
Can turn yellow and blister
Prone to blistering
Now we know what guard product do, time to understand how it works?
Each SOLID has a SURFACE ENERGY
Each LIQUID has a SUPERFICIAL TENSION
When a liquids superficial tension is less than a solids surface energy, the the liquid will penetrate into the solid.
To protect materials the aim is to reduce the surface energy of any given solid .
Guards Impregnation Fluoropolymers
Very good protection against water, solvents and grease
Very good anti adhesion properties (eg: teflon® technology)
Carbon-fluorine bonds are very steady => long lasting protection properties
Very good chemical inertness
In case of stagnant water, hydrophobic protection decreases
