Problems solved by technology

Some of these techniques are expensive, time-consuming, and can be difficult to implement on larger metal or metallized articles, and all require the use of fluorochemicals that some environmental agencies have no longer favored

[0305] Test Methods and Procedures :

[0306] Static water contact angle measurement (WCA-1)

[0307] Static water contact angles were measured on the dry treated test panels before and optionally after being subjected to the abrasion test. Measurements were performed using deionized water, filtered through a filtration system from Millipore Corporation, Billerica, MA. Measurements were performed using a DSA100 contact angle analyzer (commercially available from Krüss GmbH, Germany). Thirty seconds after deposition, water contact angles were measured for droplets with a volume of 5 μL. Contact angle values ​​are the average of measurements made on at least three droplets and are reported in degrees (°).

[0308] Water contact angle measurement (WCA-2)

[0309] Contact angle analysis was performed using a Model #500-F1 Advanced Goniometer (available from Ramé-hart Instrument Co., Mountain Lakes, N.J.) using MilliQ water as the test fluid WCA-2. Contact angle values ...

[0391] Examples EX-16 to EX-20

[0392] Examples EX-16 to EX-20 were prepared with the same treatment composition as given in Examples EX-11 to EX-15, but the stainless steel panels were treated by wipe application. The treated substrate was dried at 85°C for 10 minutes. Static contact angles (WCA-1) and decontamination performance before and after wet abrasion were measured according to the methods described above. The compositions of the treatment baths and the test results are reported in Tables 7 and 8.

[0397] Examples EX-21 to EX-24 and Reference Example REF-4

[0398] In Examples EX-21 to EX-24, stainless steel test panels were treated with a 0.1% solution of a polysiloxane functionalized with phosphonate groups (SiPhon1 to SiPhon4, respectively) in IPA. The treatment is carried out by wipe application. The treated test panels were dried overnight at room temperature. Stain release performance and...

Embodiment EX-37 to E

[0423] Examples EX-37 to EX-40

[0424] In Examples EX-37 to EX-40, the stability of treatment baths containing polysiloxanes functionalized with phosphate groups (SiPhat1) or phosphonate groups (SiPhon1) in ISOPAR L was evaluated. A freshly prepared solution of SiPhat1 or SiPhon1 in ISOPAR L was used to treat chromed ABS test panels (rinsed with IPA). Repeat the experiment with the same solution, aging for a week, two weeks or even 8 weeks. Treatment was performed by dip coating using RDC-21 equipment. The treated test panels were dried at 85°C for 10 minutes. After drying, stain release was evaluated according to the method described above. The results are reported in Table 14.

[0425] Table 14 Bath Stability

[0426]

[0427] It was observed that treatment baths containing polysiloxanes functionalized with phosphate groups or phosphonate groups in ISOPAR L had a high stability for at least 8 weeks. The soil release properties of the treated substrates were not...

Abstract

Disclosed is a composition that comprises a polysiloxane having at least one of a phosphate or phosphonate group and an amino-functional compound having at least one silane group. The method includes treating the metal surface with a composition including a polysiloxane functionalized with at least one of a phosphate or phosphonate group. The method can include first treating the metal surface with a primer composition including an amino-functional compound having at least one silane group or including an amino- functional compound having at least one silane group in the composition with the polysiloxane. Certain polysiloxanes functionalized with at least one of a phosphate or phosphonate group are also described.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application 62 / 781,500, filed December 18, 2018, and U.S. Provisional Application 62 / 932,784, filed November 8, 2019, the disclosures of which are incorporated herein by reference in their entirety. Background technique [0003] Various techniques have been used to impart repellent properties to substrates. For example, silane compounds or compositions having one or more fluorinated groups have been successfully used to impart oil and water repellency to substrates such as glass and ceramics. Such silane compounds or compositions generally already contain one or more hydrolyzable groups and at least one fluorinated alkyl group or fluorinated polyether group. See, eg, US Patents 3,646,085 (Bartlett), 5,274,159 (Pellerite et al.), 6,613,860 (Dams et al.), 6,716,534 (Moore et al.), 7,470,741 (Dams), and 7,652,115 (Dams et al.); and International Patent Application Publi...
