Q: What is the process for applying Maxon CRS?
A: Typically, pressure wash to de-grease and pressure wash again. As long as there is no loose debris, CRS will adhere to the hard rust and then to the substrate
Q: How does Maxon CRS eventually attach to the substrate?
A: Maxon CRS encapsulates hard rust to make it into a tough, corrosive-resistant barrier from the environment. CRS then continues to ionically bond to the metal below to create a corrosive resistant barrier to the base metal.
Q: What happens if Maxon CRS turns white after it cures or when it comes in contact with water?
A: Because CRS is water born there is a carrier included within the product so that when water or moisture comes in contact with CRS it may turn brown or white. This does not affect the performance of CRS. Maxon CRS is not necessarily a finish coat.
Q: What is the speed of application and time-to-recoat?
A: Maxon can be applied as a 2 coat system depending on the substrate. If the metal and rust is flat and relatively smooth a one coat system could be sufficient. However if there is a wide range of pit ridges on the hard rust, then a 2nd coat may be required. The best application method is cross hatching or north-south, east-west. The 2nd coat should be applied when 1st coat is tacking or near dry. In full sun and wind this could be as quickly as 10-15 minutes, or up to an hour in darkness or humidity.
Q: Can Maxon CRS be applied on wet surfaces?
A: Yes, if the damp surface implies a non-pooling substrate. If there is pooling, waste will occur because it will dilute the water born CRS and will adversely affect its anti-corrosion properties.
Q: Does Maxon CRS adversely affect any other materials such as plastic, rubber, silicone?
A: Not at all. This is part of our advantage. For example, if coating the chassis of a car, CRS will not harm the rubber or the isolation of any electric wiring.
Q: Is the product recommended to be used before welding or after? Is Maxon CRS conductive or not?
A: Both! Standard Maxon CRS is conductive. Just coat and weld joints afterwards. However, if you need your surface to be non-conductive? Maxon CRS can also be formulated to inhibit conductivity to provide insulating properties as well.
Q: What happens when the coating is breached/damaged and the metal below is exposed?
A: One of the best characteristics of CRS is that it will not allow corrosion transmission beyond the damaged area. Only the exposed/damaged metal will be affected by the environment and can be repaired with CRS as needed. CRS is a fairly durable coating and should withstand normal abrasions.
Q: What is the theoretical estimate on Maxon CRS product life expectancy coated surfaces.
A: 10 Years or more.
Q: When can top coats be applied to Maxon CRS?
A: Tacky to dry is the key state to look for when waiting to top-coat. Maxon CRS operates under 2 conditions: 1: because CRS is water born, the first state is “water release” which takes some time. 2, its second state is a chemical cure period which encompasses corrosion and binds ionically to the metal substrate. The chemical cure may occur during or after a top coat is applied (48 hours) but it is imperative that Maxon CRS is dry to the touch before any top coat is applied.
Q: Any hints or best practices for applying CRS?
A: Always stripe any edge either with a spray brush or roller because CRS is water born there will be shrinkage as it cures. We recommend a 25% over-spray with airless or conventional spray equipment. A 519 tip or larger orifice is preferred due to the viscosity of CRS. Spraying too thick of a 1st coat will delay cure time and decrease the bonding between 2nd coat, paint and/or epoxy top coat. If rolled or brushed short nap rollers are preferred in a light touch over the substrate or completely covering it with CRS. Well joints and pitted areas should be brushed to insure complete coverage and penetration. Any corroded areas with extensive pitting, jagged edges or uneven substrate should be double coated (2 coats via north south east and west pattern)
Q: Does Maxon CRS actually penetrate paint?
A: Yes. We have extensive test results from Cal Poly San Luis Obispo that confirm through (SEM Testing) that interaction between CRS and existing paint and metal substrate, penetration Not only occurs, but in some test CRS manages to permeate the full thickness of the metal test sheet. Photos and literature are available, contact us for more.
Q: Why should I use Maxon CRS?
A: The highest costs in time and money for any repair/maintenance schedule can usually be found in prep equipment and labor. The single most obvious advantage for CRS is requiring less costs in each of the above resources. Depending on a contractor’s region, sand blasting, hand tooling/grinding costs that meet or exceed standard preparation requirements (SSPC, ASTM, Etc.), will far exceed the price of A Maxon CRS treatment and related installation protocol.
