It is well known that Cortec's M series products are effective anti-corrosion additives that can be used for different applications.

M-640 L
M-640 L is an excellent addition to Cortec's line of additives. This is a liquid version of M-640 powder. Both products are corrosion inhibiting additives for water/ethylene glycol radiators. For customers who prefer to use liquids, M-640 L will provide excellent multimetal protection. This product contains a unique combination of contact and vapor phase inhibitors, which help to prevent corrosion even in partially filled spaces.Engine antifreeze/coolants treated with the recommended concentration of M-640 L will pass ASTM D-1384-87 (Standard Test Method for Corrosion Test for Engine Coolants in Glassware).

Unlike many conventional products, M-640 L does not contain phosphates nor nitrites. M-640 L is also silicate-free. Silicates have a tendency to precipitate from the solution and clog filters.

M-380 and M-119
You may already be familiar with these two anti-corrosion additives for coatings. M-119 has been in Cortec's product line for several years. M-380 was introduced in an earlier newsletter. Both products are very effective additives to coatings. It was shown that for some carboxylic primers, such at latex-based products, a blend of M-380 and M-119 (2:1) in small concentrations greatly improve the anti-corrosion properties.

The addition of 2% M-380 and 1% M-119 to such coatings increased protection time in salt spray environments from 160 hours for untreated coatings to 800 hours for treated. In addition, these additives will not increase the VOC (Volatile Organic Compound) level in the final coating as they are water-based. Also, important coating properties such as adhesion and flexibility will remain unchanged.

VCI-415 Aircraft Cleaner
We are proud to announce our very new alkaline cleaner, which conforms to established specifications for aircraft cleaners. VCI-415 is a heavy-duty water-based alkaline cleaner and degreaser offering unique multimetal corrosion protection for up to 6 months (indoor storage).

VCI-415 can be effectively used on aircrafts for cleaning and protection, on machinery contaminated with oils, metal parts contaminated with stamping, drawing and buffing compounds.

VCI-415 is VOC-free and environmentally friendly.

VCI-411 and VCI-411 Gel
These two new cleaners/degreasers are excellent additions to Cortec's line of biodegradable products. They are both based on D-Limonene, which is the hydrocarbon extract from orange and lemon peels. Because of their similar nature to hydrocarbons, D-Limonene-based cleaners act very similarly to hydrocrabon solvents, removing greases, paraffins, and waxes. VCI-411 is a microemulsion which contains corrosion inhibitors and D-Limonene with water. This product is a clear liquid which can be diluted with water up to 1:20. This is a great feature of this product. They also leave residue on metal surfaces after application where VCI-411 does not. VCI-411 Gel is a thixotropic version of VCI-411, designed to remove heavy oils and grease from vertical surfaces and hard to reach areas. Both of these products also will remove waxy temporary coatings such as Cortec's VCI-368. VCI-411 and VCI-411 Gel have a very pleasant odor, are non-toxic and user-friendly.
